The spec madness continues with the 13MP ISOCELL camera with an f/1.8 lens, PDAF, OIS, dual-tone LED flash and a pixel size of 1.34um, and a front 8MP camera with larger 1.4um pixels. There's a heart rate sensor at the back, which can also measure oxygen saturation. The 5.2-inch Super AMOLED Full HD display sounds mundane compared to the rest of the specs on offer, but it does go up to 500 nits, and down all the way to 1 nit, allowing you to read at night. It also sports 100 percent NTSC and sRGB color gamut. When it comes to the software, you get Marshmallow out of the box with ZUK's custom UI.

You also get a fingerprint sensor at the front, and the phone features a shock-absorbing layer between the glass back and the metallic frame that's designed to protect the device when it takes the inevitable tumble. The only thing that's missing from the phone is NFC.

The price, you ask? The variant with 6GB RAM and 128GB storage is set to retail for ¥2,699, which comes out to $420. No mention if the phone will be available in global markets, although a spokesperson revealed to Engadget that sales will continue in the Middle East and European markets.
